Throwing an exception in debug mode only doesn't seem to provide much value.  When debugging, you might as well just halt the program at the problem, which boils down to simply assert(precondition_is_true).  This pinpoints the problem source and relieves the user of writing debug-only catches, as well as other exception-on-precondition-violation pitfalls.

The precondition violation topic has been thoroughly discussed.  For a summary, see: http://www.boost.org/more/error_handling.html
